Vulnerability in Kernel (CVE-2022-49151)

Summary

Vulnerability in Kernel (CVE-2022-49151). Risk of unauthorized operations or information disclosure. Mitigation: upgrade to 4.14.276, 4.19.238, 5.4.189, 5.10.110, 5.15.33, 5.16.19, 5.17.2 or later.

Original description

The description as published by the source.

In the Linux kernel, the following vulnerability has been resolved:

can: mcba_usb: properly check endpoint type

Syzbot reported warning in usb_submit_urb() which is caused by wrong
endpoint type. We should check that in endpoint is actually present to
prevent this warning.

Found pipes are now saved to struct mcba_priv and code uses them
directly instead of making pipes in place.

Fail log:

🔧 How to fix

Update to 4.14.276, 4.19.238, 5.4.189, 5.10.110, 5.15.33, 5.16.19, 5.17.2.

🛡️ Workaround

Until the patch is applied: disable the affected feature, apply WAF rules, or restrict access via network ACLs.

🔍 Detection

Search webserver/proxy logs for unusual request patterns matching this CVE's known IOCs. Run grep -r 'Kernel' . against your dependency files (package-lock.json, requirements.txt, go.sum) to find affected services.

Response actions

Concrete steps and command examples for SOC/SRE teams to execute in order

1
Identify exposure identify
```
grep -r 'Kernel' . | grep -v node_modules
```
リポジトリと本番環境の依存ファイル (package-lock.json / requirements.txt / go.sum / Gemfile.lock 等) で Kernel を grep し、稼働しているサービス・バージョンを把握する。
2
Apply patch patch
```
Upgrade Kernel to 4.14.276, 4.19.238, 5.4.189, 5.10.110, 5.15.33, 5.16.19, 5.17.2
```
ステージング環境で 4.14.276, 4.19.238, 5.4.189, 5.10.110, 5.15.33, 5.16.19, 5.17.2 に上げて回帰テスト → 本番反映。回帰テストはアプリの主要ハッピーパスを含めること。
3
Post-deployment verification verify
```
Confirm patched version is live in production
```
パッチ適用後、ステージングで PoC または同等の悪用パターンを再現して脆弱性が閉じたことを確認。本番ではアクセスログ・WAF でアラート再発が無いか継続監視。
